Fix up navigability of exercise hints. Fixes T3680.

Summary:
This makes it so that when you click the "Get Hint" button the screen reader will read off the newly-added hint.

Additionally I made the individual hints navigable using a screen reader (gave them a tab order).

Test Plan:
View an exercise with a screen reader turned on. Navigate to the hint button and press enter. You should hear the newly-added hint read off.

You should be able to navigate to hint using your keyboard, as well.
